Ben Affleck and Jennifer Garner announced their separation nearly six years ago after 10 years of marriage, but the former couple still share a sweet bond. On Mother's Day Sunday, Affleck shared a touching tribute to Garner, who has three children, 15-year-old Violet, 12-year-old Seraphina, and 9-year-old Sam.

Affleck included a series of amazing snaps featuring himself, Garner, and their children in Wizard of Oz family Halloween costumes (Affleck as the Tin Man, Garner as Glinda the Good Witch, and the kids as Dorothy, the Scarecrow, and the Lion) He shared throwback photos on Instagram. He also recorded, presumably for the children, Garner saying, "Shhh, don't tell anyone. Bye!"

"So happy to share these kids. They are the luckiest parents in the world. Thank you for everything," Affleck captioned the post.

"Happy Mother's Day. Love you, daddy of these babies. Cute!

Last year, Affleck spoke to People (opens in new tab) about his relationship with Garner following their divorce, which was finalized in 2018. "When you have a child with someone, you're connected to that person forever." And I feel very fortunate that she is the mother of my children."

"I'm very grateful and respectful of her," Affleck continued. 'Our marriage didn't work out, and that's a hard thing to do. We both really believe that it's important for kids to see their parents respect each other and get along, whether they're together or not."

"It's important for my kids to know that I respect and care about Jen and that she treats me the same way. I have so much respect and appreciation for her." And I wish her all the best."
